The brickwork isopod gets its name from its interesting habitat choices. It is most commonly found in rock piles, on brick window sills, or in pebble-laden landscaping. It can also be found on or around dead, standing trees. Possibly the most intriguing trait of this crustacean is its cold tolerance. On several nighttime trips outdoors during the winter months, I have found large groups of this species on the sides of trees. Regardless of excessive snowfall or below freezing temperatures, they emerge to engage in some mystery isopod activity. Coincidentally, these are often the first isopods to actively move around in the spring, and they frequently find their way through imperfections in the sealant on my kitchen windowsill and into the kitchen sink!
